Abstract Photothermal superhydrophobic coatings are essential for a variety of applications including anti‐icing and light‐driven self‐propelled motion. However, achieving flexible durable coating with high photothermal efficiency long‐term stability is still challenging. Herein, facile eco‐friendly approach to realizing excellent flexibility proposed. The obtained by spraying titanium nitride (TiN) nanoparticles embedded in polydimethylsiloxane (PDMS) solution onto various substrates. A tight binding between the substrate occurs that offers mechanical robustness endure bending, twisting, abrasion, tape peeling. water repellency retained even after 500 cycles bending–twisting tests. Combined micro–nanoscale porous structure surface plasmonic property TiN nanoparticles, shows superhydrophobicity conversion properties. equilibrium temperature as 130 °C at room under 1 W cm −2 808 nm near‐infrared laser irradiation. Due its property, can be easily applied irregular surfaces, which, together anticorrosion, anti‐icing, defrosting performances, makes it reliable resource multifunctional applications. This work novel technological devices, wearable electronics, smart textiles.
